MANUFACTURER: Pratt & Whitney
SUBJECT: Airworthiness Directive 2004-14-22
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
Pratt & Whitney Canada (PWC) PW206B engines that have
incorporated PWC Service Bulletin (SB) No. 28119, and PW206C,
PW206E, PW207D, and PW207E turboshaft engines. This AD requires
checking the automatic low-cycle-fatigue (LCF) counting data made
by the engine Data Collection Unit (DCU) on installed engines, and
validating proper DCU automatic LCF counting before an engine is
installed.
